What’s New in Version 6.x Series
Menu Update
Reporting Control has been changed to CXtra Preference. This
command change appears on the Cxtra Services menu and on the
related dialog. Use this dialog to disable the beeping sound that
occurs with some software functionality.
Front Sensor Scheduling
The functionality for specifically scheduled front sensor testing has
been eliminated. You can elect to run front sensor testing
automatically and manually. Automatic testing occurs each day.
Dome Displays
Dome CXtra support has been added for the Dome GX4MP display,
a 4-megapixel color unit with DVI video connectivity.
Support was added in previous versions of Dome CXtra for the
GX2MP Plus display, a 2-megapixel color unit with DVI connectivity;
Dome E3cHB and Dome S3c displays, both 3-megapixel color units,
and Dome S3, a 3-megapixel grayscale unit, all with DVI and
DisplayPort video connectivity; and the Dome S10 display,
a 10-megapixel grayscale unit with video input via DVI connectivity.
MQSA Test Service
You can set up test reminders for consistent quality control activity
and record the results of the quality control tests electronically.
NOTE: Applies to Dome E5 and Dome S10 displays only.
Expansion of Manual Conformance Testing
With the addition of the front sensor on some models of Dome
displays, the Manual Conformance functionality has been bifurcated
into the External Sensor Conformance testing (using the photometer
device) and the Front Sensor Conformance testing.
External Sensor Conformance replaces Manual Conformance on the
CXtra Services menu and the Conformance wizard. All operational
procedures are unchanged.
Front Sensor Conformance has been added to the menu. With this
functionality you can perform auto and manual conformance testing.
NOTE: Applies to Dome S3, Dome S3c, and Dome S10 displays only.
White Level Maximum Limit Exceedance
If you have a requirement to exceed the maximum limit of the preset
White Level target range, you can now do so but your display
warranty becomes void. Contact NDSsi Customer Care for more
information.
European Reference Guidelines
The EUREF guidelines, organized by the European Reference
Organization for Quality Assured Breast Screening and Diagnostic
Services, promotes mammography care of high quality in European
Union member states. Users of Dome displays qualified for AAPM
TG18 can perform the White Level Calibration procedure to meet this
standard. See “White Level Calibration Service” on page 44.
Modification of Color Calibration Setting
Only an administrator, not privileged users, can modify the color
calibration setting accessible on the RightLight Panel Configuration
dialog, Color tab. (See page 22.)
NOTE: Applies only to Dome displays using the RightLight
functionality.

Windows Platform Support
Support is available for the Microsoft Windows 7 (x86 or x64) and
Windows Server 2008 R2 (x64 only) operating systems.
Support for the Microsoft Windows XP x64 operating system was
®
added to the Dome
CXtra™ 6.x series in an earlier version.
CXtra Utilities
Users can start, restart, and stop all CXtra services and application,
and run CXtradiag with utilities. Access the tools via the Windows
Start menu.
NOTE: Windows administrator privilege is required to run the utilities.
Users without privilege must enter an authorized username and
password as prompted.
Fast User Switching
The Fast User Switching feature is not supported on display systems
using NVIDIA drivers previous to version 197.03.
Installation Upgrades
The installation procedure for Dome CXtra is now simpler, faster, and
more reliable. All services and features are installed by default. To
customize your installation, you must deselect the service or
application feature you do not wish to install.
White Level Calibration
Correction of the display white level can now be done via manual
conformance testing or with the White Level Calibration service.
A one-time, end-user calibration of the white level may be necessary
when the target luminance is outside the tolerance established for
proper display conformance, such as when the white level of a display
has failed a manual conformance test, or when two or more displays
in a multi-unit configuration show disparate white levels. An external
photometer is required.
What’s New in Version 6.x Series | 3
NOTE: Privileged users and administrators can calibrate the
white level if a display fails the White Level test during the manual
conformance testing. Only administrators can calibrate the white
level via the White Level Calibration service.
Support for 10-Bit Displays
You can now run the Dome CXtra software on Dome 10-bit grayscale
displays. You can check for 10-bit capability (both current and
maximum supported) on the Properties tab of the Reporting dialog.
You can also view 10-bit patterns (horizontal ramp and vertical
ramp test patterns) using the Test Patterns service. And in manual
external sensor conformance testing, you can take all 1024
measurements for more precise testing results.
Using Dome CXtra with Dome Dashboard
For best practice of using Dome Cxtra 6.x with Dome Dashboard 2.x,
observe the following requirement and recommendation.
• When using Dome Dashboard 2.x, make sure that Dome CXtra 6.x
or later is installed on each CXtra workstation.
• On the CXtra workstation, limit the retention of history to 365 days
(one year).
Single Dome CXtra Package
The separate packaging of the Enterprise Management Service has
been discarded. All CXtra services, including the Enterprise
Management Service, are now available in a single CD package.
Dome CXtra Limitation
When using a display configuration with the NVIDIA 1800 board in
Windows XP Span mode, the only video connection supported is
two (2) DisplayPort-to-DVI adapters.

Getting Started
The Dome CXtra software adds essential functionality to Dome
medical imaging display systems in diagnostic and referral settings.
By using the Dome CXtra suite of value-added services, you can
calibrate and maintain displays, run acceptance tests, and monitor
displays remotely. While the services operate as independent plugins, they each use the Reporting service for listing properties, logging
events, and saving history.
Display Compatibility
CXtra services enhance the functionality of these display systems:
•Dome Cx
•Dome Ex
•Dome Gx
•Dome Sx
• Select Desktops
You can also install the Dome CXtra software on systems using
third-party commodity monitors to enable DICOM calibration. See
“Enabling DICOM Calibration on Third-Party Monitors” on page 95.
NOTE: When you add or remove displays on the Windows desktop,
you must restart the Dome CXtra software by rebooting the system.
(Refer to ReadMe file for more information.)
WARNING: When the Dome CXtra application is running on the
system, power off the workstation before you either connect a DVI
cable to or disconnect a cable from the Dome display. Connecting or
disconnecting a DVI cable with the workstation power on may
corrupt the display EDID data.

RightLight Service
The RightLight service performs backlight stabilization,
DICOM calibration, automatic conformance testing, and manual
conformance testing via an external photometer for Dome Cx,
Dome Ex, Dome GX4MP, and Dome Sx displays. Manual conformance
testing via the display front sensor is available for Dome Sx units.
With RightLight, you can set a target white level, equalize the black
level across the displays, set a desired response function, and specify
ambient light in the viewing area. This service also reports current
white and black levels.
RightLight automatically calibrates the displays at regular intervals.
Calibration adjusts the response of a display to conform to the
response function you specify. There are four calibration response
functions, one of which is a correction to the DICOM Grayscale
Standard Display Function.
DICOM calibration is based on the unique characteristic curve stored
in each display at the time of manufacturing. RightLight routinely
checks how well each display conforms to the DICOM standard and
calculates a Luminance Uniformity Metric (LUM) value that indicates
the degree of conformance.
Besides the automatic conformance testing and adjustment that
RightLight performs regularly, you can perform manual external
sensor conformance testing, using an optional photometer. On
Dome Sx displays, you can also perform manual conformance testing
with the embedded front sensor photometer.
RightLight Service | 15
You can also calibrate the internal RightLight photometer to generate
a new calibration data file whenever the white level is outside the
tolerances set for the display configuration. Calibrating the white
level requires an external photometer.
For Dome Ex, Dome GX4MP, and Dome Sx color displays, you can set
color coordinates for panel appearance in one of two ways:
• Select an option for panel appearance with blue, clear, or default.
• Use the LCD II photometer to perform color calibration
when you specify color coordinates by color temperature
(Kelvin scale) or by CIE xy coordinates.
NOTE: Setting nondefault color coordinates can change the target
luminance range.

NOTE: If you set the white level too close to the maximum brightness
capability of the display, frequent warnings on high white levels may
appear. To correct this problem, reduce the white level setting on the
Backlight tab until the warnings stop appearing or use the CXtra
Preference dialog to disable the warning popups. If you have a requirement to exceed the maximum limit, you can do so but you void your
display warranty. Contact NDSsi Customer Care for instructions.
Dome CXtra gives you three options for controlling dynamic range.
• Maximize - Causes each selected display to be calibrated using its full
dynamic range. The range of the selected displays may differ.
• Equalize - Causes all selected displays to be calibrated using the same
dynamic range. The system locates the selected display that has the
smallest dynamic range and adjusts the range of the other selected
displays to match it.
• Specify - Causes all selected displays to be calibrated using the
specified dynamic range. The system notifies you if any of the
selected displays cannot achieve the specified range.
If all the selected displays have similar dynamic range, there may be
little or no visual difference among the selections.
The black levels and white levels shown on the Backlight tab include
the ambient light level specified on the Ambient tab. NOTE: Choosing
the Native or the No RightLight Calibration option on the Calibration
tab or on the services menu prevents RightLight from equalizing black
levels. When you do this, you are no longer applying DICOM calibration.
RightLight Service | 19
Calibration tab
Select one of these response functions for auto-calibration:
• DICOM Response Function (default) – Calibrates to the DICOM
Grayscale Standard Display Function. See DICOM PS 3.14-2000
(Digital Imaging and Communications in Medicine (DICOM),
Part 14: Grayscale Standard Display Function).
• Exponential (log linear) Response Function – Calibrates to an
exponential (log linear) response function. The logarithm of
the luminance is a linear function of the digital driving level.
• Native Response Function – Automatically sets the flat panel to its
native response function (characteristic curve). The characteristic
curve is the response function of the panel with no calibration
applied. This is the display function created by loading a linear
gamma correction table, or GCT.
• No RightLight Calibration – Turns off auto-calibration. Choose this
response function if you are using an external calibration product
such as the Dome Calibration TQA™ system. Dome CXtra retains
GCTs currently set or created by an external calibration. RightLight
stabilizes the backlights only.
CAUTION: Do not calibrate with an external calibration product,
such as the Dome Calibration TQA system, unless your response
function is set to No RightLight Calibration. Otherwise, RightLight
overwrites the gamma correction table.
Check the selection box for each function you want to place on the
services menu, then change the operating parameter via the menu.
20 | Dome CXtra
Ambient tab
Specify the ambient light in the viewing area. Select the ambient light
description that best fits the display location:
2
• Low (reading room - 0.20 cd/m
• Moderate (typical office - 0.80 cd/m
• High (brightly lit office - 1.50 cd/m
• Custom – Fill in a value ranging from 0.00 (default) to 5.00 cd/m
The RightLight service allows you to enter luminance in cd/m
resulting from the diffuse reflection of ambient illuminance.
Since typical Dome panels have a reflectance of 1.25%, given
illuminance E in lux, you can calculate the luminance in cd/m
using this equation:
)
2
)
2
)
2
.
2
2
luminance = 1.25% × E /
π
The default values are typical of reading rooms (approx. 50 lux),
moderately bright offices (approx. 200 lux), and brightly lit offices
(approx. 375 lux).
NOTE: Choosing the Native or the No RightLight Calibration option on
the Calibration tab or on the services menu prevents RightLight from
correcting for ambient light. When you do this, you are no longer
applying DICOM calibration.
RightLight Service | 21
Color tab
Specify the panel appearance of Dome Ex, Dome GX4MP, and
Dome Sx color displays, with or without calibration.
Appearance. Use options in the Appearance field to specify blue,
clear, or default when you do not color-calibrate the display panel.
Calibrated color coordinates. Use options in the Calibrated Color
Coordinates field for precise specification of color coordinates. Apply
this method, for example, with multiple displays when a discrepancy
appears in color matching after you have selected an option in the
Appearance field.
NOTE: Only an administrator, not privileged users, can modify the
color calibration setting. The functionality is enabled only when the
administrator is logged onto the system.
First, click Color Calibrate to run the calibration wizard. Next, test and
accept the calibration. Then, set the color temperature by Kelvin
scale (from 5000 to 12000) or specify the CIE xy coordinates. Click
Apply or OK to finish.
NOTE: The LCD II photometer is required for color calibration of
the Dome color displays.
22 | Dome CXtra
Front Sensor tab
Specify the front sensor conformance test(s) you want RightLight to
run. You can schedule testing to run automatically each day and
conduct testing manually.
RightLight alerts you of a failure in these three ways: by message, by
entries in the History log, and by status change of the Dome CXtra
icon in the system tray. If the CXtra-enabled workstation is connected
to Dome Dashboard, an alert is also sent to the Dashboard app or
SNMP console.
To set auto alert parameters
Click the selection box for the automatically scheduled and manual
tests you want to run.
• For the RightCheck White Level test, enter a value for Tolerance ±.
Then check the scheduled or manual selection box, or both, for test
alerts. The RightCheck White Level test is classified a failure if the
measured white level is outside the range defined by this percent,
applied to the Target Luminance defined on the Backlight tab.
Enter a value ranging from 0 (zero) to 25 (default = 10.00). Tests
producing a white level value outside of this percentage range
generate a warning message.
EXAMPLE: Target white level: 600 cd/m
2
Tolerance: ±10% Result: Values outside the range from 540 to 660
(600 ± 60 cd/m
2
) indicate a test failure.
RightLight Service | 23
• For the DICOM LUM test, enter a value for Maximum allowed.
Then check the scheduled or manual selection box, or both, for test
alerts. The DICOM LUM test is classified a failure if it produces
a value greater than the maximum allowed. Enter a value ranging
from 0 (zero) to 2 (default=1.00). A value of 0 (zero) indicates
perfect conformance with the DICOM Grayscale Standard Display
Function. The DICOM LUM Test assesses the standard deviation of
JNDs (Just Noticeable Differences) per digital interval.
EXAMPLE: Maximum allowed: 1.00 Result: A test result of 0.421
passes, because it is less than 1.00.
Enter the number of measurement you want the system to take for
this test. For the front sensor, the default number of measurements is
15; the minimum,5; the maximum, 32 (All).
If you run the Front Sensor Conformance Wizard with the selection
boxes unchecked for both the DICOM LUM test and the White level
test, you are logging the data from a completed conformance test
without applying the criteria of the DICOM LUM and White Level tests
for Pass/Fail determination.

Rear Sensor tab
Specify the conformance test(s) you want RightLight to run. Every
5 minutes, RightLight automatically performs the tests selected on
this tab. For each test you select, you can specify a threshold value
that defines a test failure. RightLight alerts you of a failure in these
three ways: by message, by entries in the History log, and by status
change of the Dome CXtra icon in the system tray. If the CXtraenabled workstation is connected to Dome Dashboard, an alert is also
sent to the Dashboard app or SNMP console.
To set alert parameters
1 For the rear (backlight) sensor, select either the RightLight White
Level test or the DOICOM LUM test, or select both.
For the RightLight White Level test, check the selection box. Then
enter a value for Tolerance ±. The RightLight White Level test is
classified a failure if the measured white level is outside the range
defined by this percent, applied to the Target Luminance defined
on the Backlight tab. Enter a value ranging from 0 (zero) to 25
(default = 10.00). Tests producing a white level value outside of this
percentage range generate a warning message.
EXAMPLE: Target white level: 600 cd/m
2
Tolerance: ±10% Result: Values outside the range from 540 to 660
(600 ± 60 cd/m
2
) indicate a test failure.

For the DICOM LUM test, check the selection box. Then enter
a value for Maximum allowed. The DICOM LUM test is classified
a failure if it produces a value greater than the maximum allowed.
Enter a value ranging from 0 (zero) to 2 (default=1.00). A value of
0 (zero) indicates perfect conformance with the DICOM Grayscale
Standard Display Function. The DICOM LUM Test assesses the
standard deviation of JNDs (Just Noticeable Differences) per digital
interval.
EXAMPLE: Maximum allowed: 1.00 Result: A test result of 0.421
passes, because it is less than 1.00.
2 In the Log interval section, enter a time interval and starting time
for the first daily test in the hours starting at field. RightLight logs
the first set of conformance tests at the time specified and at
regular intervals thereafter until the end of the day.
Enter a positive integer for hours and a time in the 24-hour format,
such as 13:30. This interval specifies how often the system logs the
results of the selected test(s).
When a selected test fails, a message appears and the CXtra icon
changes to indicate a warning state. View the test results in the
Reporting History log.
NOTE: The log interval and start time must apply to all displays.
These fields are not enabled unless all displays are selected.
